[tex]x + \frac{3}{2} = \frac{x}{3} \\ 6x + 9 = 2x \\ 6x - 2x = - 9 \\ 4x = - 9 \\ x = - \frac{9}{4} = - 2 \frac{1}{4} [/tex]
Myślę że pomogłem ;)
[tex]x+\frac{3}{2}=\frac{x}{3}\,|\cdot3\\\\3x+\frac{9}{2}=x\\\\3x-x=-\frac{9}{2}\\\\2x=-\frac{9}{2}\,|\div2\\\\x=-\frac{9}{2}\cdot\frac{1}{2}\\\\x=-\frac{9\cdot1}{2\cdot2}\\\\\boxed{x=-\frac{9}{4}=-2\frac{1}{4}=-2{,}25}[/tex]
